## What it is
DataX is Alibaba's open-source offline data synchronization framework, the open version of Alibaba Cloud DataWorks data integration. It syncs data between heterogeneous data sources (MySQL, Oracle, HDFS, Hive, HBase, MaxCompute, etc.) via a pluggable Reader/Writer architecture.

## Use cases
- sync data from MySQL to Hive
- migrate an on-prem Oracle database to cloud storage
- bulk load data into MaxCompute or Hologres
- copy tables between heterogeneous databases
- batch export HDFS data to a relational database
- set up scheduled offline ETL pipelines between data sources

## When to choose
- you need batch/offline data sync between many heterogeneous sources
- you want a plugin-based framework you can extend with custom readers/writers
- you're already in the Alibaba Cloud ecosystem and want the open-source counterpart of DataWorks integration

## When to avoid
- you need real-time streaming/CDC sync (DataX is primarily offline batch)
- you want a lightweight single-database migration tool
- you need a fully permissive license (license is marked NOASSERTION)

## Facets
- artifact type: framework
